This matched trio was carefully removed together from a highly specialized railroad system’s 300V regulated power supply chassis used in railroad control tower operations. This industrial-grade iron is incredibly over-engineered, making it a premium choice for high-end custom tube amplifier builders, audiophile DIY hi-fi projects, or vintage radio restorations. Why this set is ideal for Tube Amp Builders: Continuous Duty Iron: Built to zero-compromise railroad safety standards for 24/7/365 operation without overheating. Vintage Steel Core: 1950s laminations provide excellent magnetic properties and the coveted harmonic compression/”sag” that modern transformers cannot mimic. Ultra-Quiet DC Filtering: The matched L1 and L2 choke coils provide a massive advantage for smoothing out high-voltage ripple, delivering a dead-silent noise floor for sensitive audio circuits. Included in this set:(1). Main Power Transformer: Style HT / Volts: 115 / Cyc: 50/100(2) Matched Filter Choke Coils: L1 and L2 inductors matching the power transformer chassis requirements. All components feature the original, intact Union Switch & Signal identification tags complete with factory serial numbers. Physical Condition: Excellent vintage condition.
